SIGNALING DEVICE.

Specificaton of Letters Patent.

Patcnted Mar. 7, 1916.

Application filed July 25, 1914. Serial No. 853,()86.

,sding at Le Mars, in the County of Plymouth and State of Iowa, have invented certain new and useful linprovements in Signahng Devices; and I do hereby declare the following to be a full, clear, and exact description of the inventicn, such as will enable others skilled in the art to which it appertains to make and use the same.

'I his invention relates to new and useful improvements in signaling devices, and has ter its principal object to irovide a device which is particularly adapted for use on street cars or similar vehicles.

Another object of the invention is to provide a simple and effective device which will give a sign-al when a vehicle is about to stop or has come to a standstill.

A further object of the invention is to provide an automatic circuit Closer which is operated through centri'i'ugal force and indicates to tne user the fact that a vehicle has stopped or the speed retarded.

With these and other objects in view, the inventic-n consists in the no-vel combination and arrangement of parts which will be fuliy set for-th in the following' specication and accompanyng drawings, in which Figure 1 is a side view in elevation of a signaling device constructed in accordance with this invention and showing the same w th the circuit open. Fig. 2 is a longitudnal sectiCn-al view illustratin g, the device with the circuit closed. Fig. 3 is a top plan view of the device. Fig. e is a fragmentary sectional view taken Cn line of Fig. 2, and Fig. 5 is a view similar to Fig. el lool:- in' in the direction of the arrow.

Referring now to the drawings by characters of reference the numeral l designates the base plate of the device having secured thercto the upstanding` cvlindrical member 2. This cylindrical member is provided at its upper extrcmitv with the reduced cylindrical extensicn 3 which forms the shoulder the use of which will appear as the description proceeds.

Rctatably mounted on the stem 2 is the sleeve 5 having formed at its lower end the wheel 6. The upper end of this sleeve is provided with the laterally extending arms 7 which are spaced from' each other to form 5 the Slots S.

Pivotally mounted between the arms 7 as which the pivot pin 12 is extended.

at 9 are the arms 10 carrying at their lower terminals the reduced extensions 11 through An arcuate lateral extension 13 is formed on each of the arms and is provided with a plurality of apcrtures 14:, the use of which will appear as the description proceeds. Fcrmed laterally of the upper ends of the arms 10 are the enlargements 14 which are provided with the upstanding members 15 and 16 carrying the insulation 17, which is arranged to support the contact plate 18.

Pivotallv secured to the pin 12 intermediate its ends is the lever 19 carrying at its lower terminal the weight 20. The upper end of this lever is provided with a suitable aperture through which a pin 21 is arranged 'to extend. This pin 21 is so arranged that it projects through the apertures l l hereinbefore referred to, and thus holds the lever 19 in adjusted position with relation to the arms 10.

A suitable di k 22 having the central aperture 23 formed therein surrounds the upstanding; portion 3 ot' the stem 2 and said dish is provided with the transverse groove 24, which is arranged to register with the aperture toi-med in the extension 3 to receive the pin 26, by means of which the disk 22 is held in place. A suitable annular recess 27 is formed inthe under face of the disk 22 and forms the fiange 28 upon which the insulating' material 29 supporting the contact ring 30, is Secured. A suitable longitudinai aperture 31 extends through the disk 32 near the aperture 23 and is arranqed to form a passage for a suitable lubricant by which the sleeve 5 may be lubricated to permit the same to rotate freely on the stern 2.

A suitable ring 32 having the enlarged central aperture 33 'formed therein. is arranged to fit the disk 22 and be supported thereon by means of the screw 33 This ring is provided with an internal recess 34, the walls of which support the insulating material 35, by means of which the contact ring 36 is supported. This contact ring is connected to a suitable wire 37 which establishes communication between the contactring and the signaling device designated by the numer-al 38. The opposite terminal of the sie'naling device is connected to the wire which is in turn connected to one pole of a power source 40. The opposite pole of the power source 40 is connected by means of the Wire 41 to the contact plate 30 and thus When the contact plate 18 engages both of the contact ri'ngs 30 and 36, it Will be apparent that the circuit Will be completed through the signaling device, and thus a Warning given.

From the foregoing it Will be apparent that in use When the levers 9 are in the position illustrated in Fig. 2, the signal will be given and indicate that the Vehicle is at a standstill. Upon movement of' the vehicle it will be apparent that power Will be transmitted to the Wheels 6 `which will cause the sleeve to revolve, and thus Swing the arms 19 outwardl y into the position illustrated in Fig. l, which Will break the circuit and thus cause the signal to stop.

While in the foregoing there has been shown and' described the preferred embodiment of this invention, it is to be understood that such changes may be made' in the combination and' arrangement of parts as Will fall within the spirit and scope of the inrention as defined in the appended claims.

Having thus described my invention, I claim:

l. A device of the character described comprising a base plate, a central upstanding cylindrical member formed on the base plate, a sleeve rotatably mounted on the central cyl'ndrical member, a drive wheel on the sleeve, arms extending laterall'y from the upper terminal' of the sleeve arms pivotal'ly Secured to the arms and arranged. to Swing outward'ly, contact plates carried by the pvoted arms, a ring supported on the upper end of the upward extension of the base plate, a ring supported on the upper end of the cylindrical extension on the base plate, a ring surrounding the disk, and a pair of contact rings carried by the disk and rings and arranged to coperate With the contact plates carried by the arms and completing an electrical circuit.

2. A device of the character described comprising a base plate, an upstanding cyindrical extension formed centrally of the base plate, reduced cylindrical extension at the free terminal of the upstanding 'cylind-rical extension, a sIeeVe rotatably mounted' on the upstanding extension, a drive wheel carried by the sleeve, a pair of arms extending` laterally from the sleeve, a pair of p voted arms secured to the laterally extending arms, Weights carried by the pivoted arms, said pivoted arms being arranged to Swing outwardly When the sleeve is rotated, contact plates carried by the pivoted* arms at their upper terminals, a disk mounted on the reduced extension on the cylindrical portion, a ring surrounding the disk and arranged to be secured thereto, and' a pair of contact rings adapted to coopera-te With the contact plates to close a circuit through an electrical signaling de' Vice.

In testimony Whereof I afiix my signature in presence of two witnesses.
